Nice build man. I would have a little bit of concern about the rear mount on the control arms. Who was this designed by? Was any 3d modeling and/or finite element analysis done on it? I would want to be damn sure that it was solid, and even over-engineered.

I hear you! It was originally designed by the lead Race Engineer at Nissan Motorsport SA. We have since decided to change it up as another friend of ours voiced concerns about the increased vector forces with the new arms.

So we have changed the design of the rear mount, what we did was I have a friend with a late model BTCC car and we took the magnesium mount from his car and got a reproduction made up in Ally. Much more peace of mind. Speaking of which he also has CAD designs of the actual arms so we will also get those made up in the future but for now the Chromoly will be fine.

For now the thing that has been preoccupying our mind is the rear suspension. We pulled it out to for the last time. I'm not all that sure on using the Poly Propelene trailing arm bushes so they will more than likely be changed out. I would like to use spherical bearings but we're just not in the mood to come up with a solution so something bolt on a like a delrin bush.

We also had a bit of a time. We considered using a small case differential as it is lighter. We have the differential cooler So the heat wouldn't be a problem but we decided against it due to lack of ratios and the fact that 2 of our reputable engine tuners have said that the spider gears are much weaker than the ones in the Med Case.

The reason they are special is because they were given to us for free from Nissan Motorsport, with about 200 Track KM on them, so basically brand new. Quite a cool deal.

They are just run of the mill AP Discs though.

@bergie_318is The motor is lying at my tuners place, as we don't have space to keep it at our house.

Yes, that makes them special in my book, too.

looks sweet
+1 on the cat ha

great build, will be FUN when done

[SA E30]

Yeah, the hats are. It's just the discs that we are contemplating using. Although we do have a brand new set of discs. Just nice to have 2 spare sets.

does that mean they are 5x114?

Those discs are nice, but why are they special?
